替牙期骨性Ⅲ类单侧完全性唇腭裂患者修复术后口周力的分布特征

目的:通过与同龄非唇腭裂正常 儿童比较,研究替牙期骨性Ⅲ类单侧完全性唇腭裂(unilateral cleft lip and palate,UCLP)患者上下颌不同位点口周力的特征。 方法:选取替牙期6～12岁UCLP患者20例(男14例,女6例)为UCLP组;同龄正常 儿童21例(男14例,女7例)为对照组。采用口周肌压力采集系统测量每个研究对象息止 位时双侧上下颌中切牙、尖牙或乳尖牙、第一前磨牙或乳磨牙、第一恒磨牙的唇颊、舌腭侧龈缘的口周力。使用SPSS 25.0统计软件对数据进行统计分析。 结果:1．UCLP组上颌口周力裂侧大于非裂侧( P<0.05),下颌口周力两侧无差异( P>0.05)。2. UCLP组上颌口周力大于对照组( P<0.05),两组上颌唇颊侧的口周力均在第一前磨牙/乳磨牙区最大,在中切牙区最小。3. UCLP组下颌唇颊侧口周力小于对照组( P<0.01),下颌中切牙舌侧区UCLP组大于对照组( P<0.05)。4. UCLP组上颌牙弓内外口周力差值大于对照组( P<0.05),下颌差值小于对照组( P<0.01)。 结论:替牙期骨性Ⅲ类UCLP患者口周力较同龄非唇腭裂正常 儿童存在异常。     

Comparison of clinical characteristics between burning mouth syndrome patients with bilateral and unilateral symptoms

The purpose of the present study was to investigate and compare the clinical characteristics of burning mouth syndrome (BMS) patients with bilateral and unilateral symptoms. Of 769 patients with oral burning sensation, 421 patients with primary BMS were included. Among them, 324 patients who complained of oral symptoms on both sides of the oral cavity were assigned to the bilateral group and 97 patients who complained of symptoms only on one side of the oral cavity were assigned to the unilateral group. Clinical characteristics, psychological status, and salivary secretion were compared between the two groups. There were no significant differences in the mean age, sex ratio, unstimulated and stimulated salivary flow rates, or duration of symptoms between the two groups. The bilateral group had higher levels of psychological distresses compared with the unilateral group. The bilateral group had higher prevalence rates in burning, taste alteration, and xerostomia than the unilateral group. The proportion of patients who considered dental procedures as an initiating factor of BMS symptoms was higher in the unilateral group than in the bilateral group. Conclusively, BMS patients with bilateral and unilateral symptoms had different clinical characteristics, suggesting that the neuropathic mechanisms in these two groups are different.

Unilateral pulmonary agenesis associated with oesophageal atresia and tracheoesophageal fistula: A case report with prenatal diagnosis

We describe herein a case of unilateral pulmonary agenesis (PA) with oesophageal atresia (EA)/tracheoesophageal fistula (TEF) that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4^th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.

针刺在脑卒中后单侧空间忽略康复中的疗效观察

目的:探讨针刺治疗对脑卒中后单侧空间忽略患者单侧空间忽略和日常生活活动能力恢复的影响。方法:将符合条件的69例脑卒中后单侧空间忽略患者随机分为治疗组(34例)和对照组(35例)。2组均给予常规康复治疗和常规内科治疗;治疗组在此基础上进行针刺治疗,每日1次,每次30min,每周5次。两组疗程均为4周。两组患者于治疗前及治疗4周后分别采用数字消去试验、线段删除试验、画钟表试验进行单侧空间忽略程度评定,采用改良Barthel指数(MBI)进行日常生活活动能力评定。结果:与组内治疗前比较,2组患者治疗后单侧空间忽略程度及MBI评分均明显改善(P0.05)。与对照组治疗后比较,治疗组单侧空间忽略程度及MBI评分均明显改善(P0.05),其改善单侧空间忽略的疗效显著优于对照组(P0.05)。结论:针刺治疗可明显改善脑卒中后单侧空间忽略程度,从而有效提高患者日常生活活动能力,其效果显著优于常规康复治疗。     

Prepubertal Unilateral Gynecomastia: Report of 2 Cases

Prepubertal unilateral gynecomastia is an extremely rare condition. At present, its etiology and management strategy are not well known. Two unrelated prepubertal boys of ages 8 and 9 who presented with complaints of unilateral enlargement of breast tissue are reported. Physical examination, biochemical, hormonal and oncologic work-up findings were normal. Both patients were treated with peripheral liposuction successfully. Histopathological and immunohistochemical examinations showed benign fibroglandular gynecomastia and intensive (3+) estrogen receptor expression in 100% of periductal epithelial cells. Although an extremely rare and generally benign condition, patients with prepubertal unilateral gynecomastia should have a full endocrine and oncologic work-up.     

偏侧咀嚼对大鼠颞下颌关节滑膜VEGF表达影响的研究

目的:研究偏侧咀嚼对大鼠颞下颌关节(TMJ)滑膜血管内皮细胞生长因子(VEGF)表达的影响。方法:30只大白鼠随机分为6组,实验组间断磨除右侧上、下颌磨牙牙冠至龈下,对照组未做处理,饲养条件相同。实验1组磨除牙冠后4周末、实验2、3组磨除牙冠后10、16周末处死动物,取其双侧TMJ切片免疫组化检测。结果:实验1、2、3组双侧颞下颌关节滑膜VEGF表达较对照组增强。结论:偏侧咀嚼可引起颞下颌关节滑膜损伤,VEGF参与了其病理过程。     

计算机辅助设计在单侧完全性唇腭裂婴儿术前矫治中的应用

目的:评价计算机辅助设计在单侧完全性唇腭裂患儿术前矫治中的应用价值。方法:对10例单侧完全性唇腭裂新生儿取模,通过三维激光扫描仪对模型进行扫描并实现三维重建,三维诊断设计软件模拟整个错位上颌骨各骨段的矫正过程,并输出用于矫治器加工的数字模型。快速激光成型技术恢复矫治过程的模型并制作一系列矫治器,临床应用于单侧完全性唇腭裂患儿的术前矫正治疗。结果:经过3～4个月的术前矫正,错位牙槽骨排列成较为规则的弧形;唇部裂隙宽度减小,鼻翼塌陷畸形得到改善,鼻小柱偏斜得到纠正。结论:计算机辅助设计的单侧完全性唇腭裂患儿术前矫治能实现精确、量化的矫治目标,同时减少复诊次数,是一种高效、简洁的术前矫治方法。     

偏侧咀嚼患者下颌磨牙区种植体支抗稳定性的临床研究

目的：研究偏侧咀嚼患者正畸治疗中下颌第二前磨牙和第一磨牙间种植体支抗的稳定性。方法：2006～2012年来我科进行正畸治疗的患者中,选择具有偏侧咀嚼习惯,同时因正畸治疗需要在双侧下颌第二前磨牙和第一磨牙区种植体支抗控制的病例146例,男48例,女98例,年龄18～25岁,平均21．6岁。观察咀嚼侧和非咀嚼侧种植体支抗的稳定性,并对相关因素进行对比分析。结果：本组选择病例中半年内发生种植体支抗松动者23例,共25枚种植体,其中咀嚼侧6枚,非咀嚼侧19枚,咀嚼侧发生种植体周围炎14例,非咀嚼侧38例,对双侧局部骨密度进行测定,结果显示两侧种植体支抗脱落率、周围炎发生率及骨密度均具有显著性差异（P〈0．05）。结论：偏侧咀嚼患者非咀嚼侧种植体稳定性较差,可能与局部口腔卫生不良及骨密度相对较低有关。
